15.7.2
When the CPU is placed in Idle mode and the QEI mod-
ule is configured in 16-bit Timer mode, the 16-bit timer
will operate if QEISIDL (QEICON<13>) = 0. This bit
defaults to a logic ‘0’ upon executing POR. To halt the
timer module during CPU Idle mode, QEISIDL should
be set to ‘1’.
If the QEISIDL bit is cleared, the timer will function
normally as if CPU Idle mode had not been entered.
15.8
The Quadrature Encoder Interface can generate an
interrupt on occurrence of the following events:
• 16-bit up/down position counter rollover/underflow
• Detection of qualified index pulse
• CNTERR bit is set
• Timer period match event (overflow/underflow)
• Gate accumulation event
The QEI Interrupt Flag bit, QEIIF in the IFS3 register, is
asserted upon occurrence of any of these events. The
QEIIF bit must be cleared in software.
Enabling an interrupt is accomplished via the
respective enable bit, QEIIE, in the IEC3 register.

The QEI module has four user-accessible registers,
accessible in either Byte or Word mode:
• Control/Status Register (QEICON) – Allows
• Digital Filter Control Register (DFLTCON) –
• Position Count Register (POSCNT) – Allows
• Maximum Count Register (MAXCNT) – Holds a
control of the QEI operation and status flags
indicating the module state.
Allows control of the digital input filter operation.

in Byte mode can result in partially

Either use Word mode reads/writes, or
ensure that the counter is not counting
